Abstract

In a Software Defined Network (SDN), a source SDN switch in a source geographic area generates switch performance data. The source SDN switch detects when its switch performance reaches a switch performance threshold based on its switch performance data, and in response, the source SDN switch transfers source switch information. An SDN controller receives the source switch information and selects a target SDN switch in a target geographic area based on the switch performance threshold and the source geographic area. The SDN controller transfers the source switch information to the target SDN switch in the target geographic area. The target SDN switch generates switch performance data and detects when SDN performance reaches a network performance threshold based on its switch performance data and the source switch information. The target SDN transfers SDN performance information to the SDN controller.

Dependent claims

A method of operating a Software Defined Network (SDN) to characterize SDN performance, the method comprising:

in a source geographic area, a source SDN switch generating source switch performance data, detecting when source switch performance reaches a switch performance threshold based on the source switch performance data, and transferring source switch information indicating that the source switch performance has reached the switch performance threshold in the source geographic area for delivery to an SDN controller;
the SDN controller receiving the source switch information, selecting a target SDN switch in a target geographic area based on the switch performance threshold and the source geographic area, and transferring the source switch information for delivery to the target SDN switch;
in the target geographic area, the target SDN switch receiving the source switch information, generating target switch performance data, detecting when network performance reaches a network performance threshold based on the target switch performance data and the source switch information, and transferring SDN performance information indicating that the network performance has reached the network performance threshold;
and
the SDN controller receiving and transferring the SDN performance information.
